Motor Record: Known problems with Release 6-1

The Newport PM500 driver was not issuing the correct command when it queried for
the number of axes at boot up. This resulted in a "PM500 system error" message
on the 1st axis; fixed in R6-2.

A bug was introduced with R6-0; the OMS device support was overwriting PID
parameter fields during its' normalization calculation; fixed in R6-2.

There was a bug in the logic that determines the precedence between using the
controller's or save/restore's motor position at boot-up. Negative controller
positions were not handled correctly; fixed in R6-2

The home request (HOMF/HOMR) were not cleared when a soft-limit violation
occurred; fixed in R6-2.

Due to releasing R6-1 during Newport development, R6-1 can result in linker
errors on the symbol "xpsgathering". Newport users should upgrade to R6-2.
